\begin{Description}\relax
Returns the residual degrees-of-freedom extracted from a fitted model
object.\end{Description}
\begin{Usage}
\begin{verbatim}
df.residual(object, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] an object for which the degrees-of-freedom are desired.
\item[\code{...}] additional optional arguments.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
This is a generic function which can be used to extract residual
degrees-of-freedom for fitted models.  Consult the individual modeling
functions for details details on how to use this function.

The default method just extracts the \code{df.residual} component.\end{Details}
\begin{Value}
The value of the residual degrees-of-freedom extracted from the object
\code{x}.\end{Value}
